WordPress, by default shows a number of Widget Boxes in it’s admin homepage a.k.a the dashboard. These boxes are called Meta Boxes and shows Incoming Links, Plugins Feed, WordPress.org News and other WordPress news. Since WordPress 3.1, the Network features are managed through a Network Admin Dashboard accessible to the Super Admins. This Network Admin Dashboard also features these Meta Boxes.

We can pro grammatically remove these boxes. Use the below pieces of code in your theme’s functions.php or in your plugin or wherever you are overriding WordPress functionality.
